The spectrum of imaging findings associated with intracranial germ cell tumors extends well beyond the typical suprasellar and/or pineal region masses. It is imperative that radiologists who interpret pediatric neuroimaging studies be familiar with the range of imaging findings associated with intracranial germ cell tumors, particularly as the appropriate suggestion of germ cell tumor as a diagnosis can have a significant impact on the initial surgical plan. In our case series we will review the typical imaging (CT and MRI) findings of both germinoma and nongerminomatous germ cell tumors, including metastasis and local invasion/extension. We will also review how intracranial germ cell tumors can be multifocal and how they can involve unusual areas such as the basal ganglia, cerebellum, and septal leaflets. MR spectroscopic findings associated with pediatric intracranial germ cell tumors will also be reviewed, including how these findings can be very helpful to differentiate from other similar-appearing pathologies. Finally, we will briefly discuss the treatment and prognosis of intracranial germ cell tumors. Read More

Germ cell tumors (GCT) comprise benign and malignant neoplasms arising from variation of normal differentiation of totipotent primordial germ cells. Pediatric GCT are rare, representing 3% of all malignant pediatric tumors with an estimated incidence of 0.9/100.000 children up to 15 years of age. Germ cell tumors are located in the gonads, sacrococcygeal region, retroperitoneum, anterior mediastinum and pineal gland. Herein we describe a case of fetus in fetu and maternal-fetal choriocarcinoma. Read More
